What is the role of Cookies in an HTTP request/response cycle? 

Cookies are small pieces of data stored on the client-side, and they are sent with every HTTP request to the server. They are often used to maintain state between the client and server, allowing websites to keep users logged in or remember preferences over time. While cookies can play a role in security, they do not manage encryption or serve static resources. Why other options are wrong: b) Manage API authentication and authorization : While cookies can store authentication tokens, they are not directly responsible for managing authentication and authorization—this is typically done via session tokens or JWTs. c) Encrypt HTTP traffic between client and server : HTTPS, not cookies, handles the encryption of data during transmission. d) Serve static resources like images and stylesheets : Static resources are typically served through HTTP servers, not cookies. e) Cache web pages for faster load times : Caching mechanisms are separate from cookies and are typically handled by the browser's cache or through service workers.
